Abstract: Although the growth and feed performance of the fishes after inclusion of varying doses of proteins, lipids and carbohydrate has been established by so many authors in different classes of fishes. The present research work is based on the protein concentrate variation to assess the growth performance. Inclusion of 25, 30, 35 and 40% crude protein in diet of Cyprinus carpio showed promising growth parameters in treatment 4 with 35% CP inclusion. Results revealed that fish meal can be a good choice for better economic returns from the carp culture.
